How much will the US acquire Greenland for?
I estimate a very high probability that the United States will not acquire Greenland during Trump's term. The political, legal, and diplomatic hurdles are immense, and the market appears to be assigning too much weight to headline risk and Trump rhetoric.
Analysis
An actual U.S. acquisition of Greenland would require far more than presidential enthusiasm; it would need a durable agreement involving Denmark, Greenland's own political institutions, and likely a level of domestic and international buy-in that is extremely hard to imagine. Greenland is strategically important, but that importance mostly increases the odds of deeper security cooperation, basing access, or economic inducements rather than a full territorial transfer. With less than three years left in the term, the window for negotiating, ratifying, and implementing something this extraordinary is very narrow.
Trump's past interest in Greenland does create a real tail risk, because he has shown a willingness to float unusual geopolitical deals and to treat strategic assets as transactional. If any outcome besides no acquisition happens, it would probably be an oversized package rather than a symbolic or cheap purchase, since Greenland's strategic value makes a bargain-basement price implausible. Even so, the practical barriers are so high that the base rate for an actual completed acquisition remains tiny.
At 81% for no acquisition, the market is directionally right but still seems too willing to price a meaningful chance of a historic territorial deal. I would put the probability of no acquisition materially higher, around 96%, because the crowd is likely overweighting Trump's rhetoric and underweighting the veto points, sovereignty constraints, and time required to close such a deal. In other words, this looks less like a realistic transaction market and more like a market for dramatic headlines that never quite become a completed transfer.
Arguments
For
- Arguments for Yes: Denmark and Greenland both have strong reasons to reject a sovereignty transfer, which makes no acquisition the default outcome.
- Arguments for Yes: The U.S. can pursue its strategic interests through defense agreements and investment without needing to buy the territory outright.
Against
- Arguments against Yes: Trump has previously shown interest in acquiring Greenland, so the idea is not purely hypothetical.
- Arguments against Yes: If a dramatic deal emerged, the U.S. could theoretically offer a huge package that overwhelms normal political resistance.
Key drivers
- Any acquisition would require consent from multiple political actors, making the legal and diplomatic hurdle exceptionally high.
- Trump's willingness to entertain unconventional deals keeps a small but nonzero tail risk alive.
Risk factors
- A major Arctic security shock could increase pressure for an unprecedented arrangement.
- An extraordinary bargain involving massive economic support could, in theory, change the political calculus in Greenland or Denmark.
Scenarios
Best case
The Trump administration continues to talk about Greenland but never gets close to a binding purchase, while security cooperation deepens through normal diplomatic channels.
Most likely
There is periodic rhetoric and perhaps exploratory diplomacy, but no formal acquisition is completed and Greenland remains outside U.S. sovereignty.
Worst case
An unprecedented strategic bargain is struck, Denmark and Greenland accept it, and the U.S. completes an acquisition before the term ends.

Will Stripe acquire any part of Paypal in 2026?
AI7%MKT67%Edge-60HypedI think a Stripe acquisition of any part of PayPal in 2026 is very unlikely, despite the market pricing it as a strong possibility. The main reason is that this would be a large, strategically odd, and likely antitrust-sensitive transaction with little visible evidence supporting it.

Will OpenAI or Anthropic IPO first?
AI38%MKT93%Edge-55HypedI think OpenAI is substantially less likely than the market implies to IPO before Anthropic. The stronger read from the current evidence is that Anthropic has a modest but real timing edge, so I price the Yes outcome well below the market.

"Spider-Man: Brand New Day" 3rd Weekend Box Office (Lower Strikes)
AI64%MKT10%Edge+54Hidden GemA third weekend above 66 million is a very high bar, even for Spider-Man, so I lean toward Yes. The main reason to doubt that view is that this franchise can occasionally hold far better than a normal blockbuster if audience demand stays unusually strong.
